The invention relates to fruit drying ma-V chines and has for its objectto provide a de- Avice o this character comprising a rotatable drumhaving a spiral' raceway therethrough "'5 formed froln wiping elements,4whereby as v fruit is conveyed through the rotatable drum',

it will roll throughthe s iral racewa andl therefr m dii themoisturewill be Wipe o y its passage. Y u A` further object is to form thespiral raceway `from a plurality of iiexible wiping elements which willengage the peripheries of the fruit passing through the device and wipering r the moisture therefromafter a washing op- 5 eration. A furtherobject is to formthe wiping elements from stri s -of sheet rubber havingspaced notches t rough which notchesthe frult passes as it is conveyedthrough the A further Objectis toprovide lheads the ends of the drum andhaving entrance and exit passages through which thefruit passes into thedrum for the drying operation and out of the drum after thedr ingoperation.' A further object is to rovi e-longitudinally and radiallydispose strips within the intake and discharge end of the device foradditionally wiping and cushioning articles as '80 they are introducedand discharged into-the machine, Also to dispose wiping stripsfonthewall adjacent the intake end. `A further object isto provide one ofthe' i heads of the drum with vanes vforming a fan for forcing airthrough the drum as it-rotates as an additionalfdrying means A furtherobject is to 'provide drum with inwardly extending ugsto which theflexiblelwiping elements are'attached. Also l to form the flexiblewiping `elements from two layers of flexible fmaterial, preferably rub`ber, and one of saidlayers smaller than :the other for increasing vtheflexibility ofthe other layer, but allowinga wider range of YfleXibility to the marginal edge `of the other wipingelement, sothat itwilleasily conform 1.to y* ,r
